Question

3(n-2)-1=5(n+1)

Answer 1

Are we ask to solve it for n ?
If so then first use distributive property as a * ( b + c ) = a * b + a * c
Getting this ????

Answer 2

not really can you explain it more please ?

Answer 3

Oh yes we are asked to solve for x

Answer 4

okay are you getting distributive property ? getting this ?

Answer 5

Yes I get it now my answer is n= -1 is that correct ?

Answer 6

Please check it once

Answer 7

yeah my answer is wrong ughh

Answer 8

Would you like to try for it once ?

Answer 9

I keep getting the wrong answer

Answer 10

okay let me explain it
Can you first distribute 3 over ( n - 1) ?
3 * ( n - 1 ) = ----- ?

Answer 11

3n-6

Answer 12

it would be 3n - 3 how you got 6 ?

Answer 13

how did you get 3 ? if it is 3(n-2)

Answer 14

Oops sry that was typo you are right it wd b 3n - 6 correct ,,,,, :)

Answer 15

Lol no problem ok so after we get 3n-6 what do we do with the -1 ?

Answer 16

We need to collect like terms on left hand side first 3n - 6 - 1 = ---- ?

Answer 17

3n-7

Answer 18

So on left hand side we got 3n -7 correct ?
correct now try for 5 ( n + 1 ) = ----- ?

Answer 19

-5n-5

Answer 20

We are having 5( n + 1 ) = --- ?

Answer 21

The 5 is negative

Answer 22

No it is positive see there is no negative sign in front of 5 .....

Answer 23

that is a typo

Answer 24

okay so it is -5( n + 1 ) ????

Answer 25

If so then you are right for -5n - 5
So right hand side = -5n - 5
We got equation as 3n - 7 = -5n - 5 right ?

Answer 26

Now collect like terms to one side

Answer 27

The answer will be -6.

Answer 28

why is it -6 ? can you please explain ?

Answer 29

No it is not right .....

Answer 30

\[-6-2=-8\]\[-8\times3=-24\]\[-24-1=-25\]-----------------\[-6+1=-5\]\[-5\times5=-25\]-----------------
Because when -6 is used as n, and both sides come out equal, it is -6.

Answer 31

Equation is 3(n-1) - 1 = -5(n+1)

Answer 32

That's not how it's shown in the question box.

Answer 33

no the equation is 3(n-2)-1 = -5(n+1)
can one of you show me how to the problem please I have been stuck on this question for an hour

Answer 34

ok I got it up to there

Answer 35

Now we need to collect like terms to one side can you try ?

Answer 36

subtract 7 from both sides

Answer 37

We need to add 7 on both sides on equation

Answer 38

ok so I got 3n= -5n-2

Answer 39

Please check sign of 2 ???

Answer 40

ok 3n = -5n +2

Answer 41

does n=1 ?

Answer 42

Please check this once

Answer 43

you are right up to 3n = -5n + 2
Now add 5n on both sides of equation

Answer 44

ok so 8n= 2
that can't be right
